Answer:
Inequality Form: m > 7/12
Interval Notation: (7/12, ∞)
Step-by-step explanation:
Equation: 
First step:

Second step:

Third step:

Fourth step:

Decimal: 1.4 (35 divided by 25 is 1.4)
Percentage: 140% ( move decimal point two spaces to the right)
-15d - 12 = -4(d + 3) - 11d
-15d - 12 = -4d - 12 - 11d
-15d - 12 = -15d - 12
+12 +12
--------------------------------------------
-15d = -15d
---------------------------------------------
All real numbers are the solution.
